• Sommario/riassunto: Unified life-cycle engineering (ULCE) is a design engineering environment. This book addresses ULCE approaches to design, manufacture, and application of structural components, especially for advanced military systems. Conclusions and recommendations to support the development of an effective ULCE design engineering environment are also presented.
